Specification of Letters Iatent. Patented Rug. 28, 1917.

Application filed April 10, 1907. Serial No. 867,414.

To all whom it may concern:

Be it known that I, JAMEs W. BRYQE, a citizen of the United States, anda resident of Brooklyn, in the county of Kingsand State of New York,have invented certain new and useful Improvementsin'Recorders, of whichthe following is' a specifieationfifl My invention relates toreco'rders.It has for its object to provide apparatus for'producing an indication,preferably by printing, of the data represented by devices or marksrepresenting the data of the operation or operations of a machine andpreferably of a machine other than the oneembodying my presentinvention. It is of especial value in connection with time recorders andparticularly with machines for registering the time of the beginning andthe time of the ending of an operation and the elapsed time that hasoccurred between the two operations although my invention in some ofitsbroad features is not limited to use in such machines. In theparticular machine forming an embodiment of my invention, shown in thedrawings herein, I have shown an apparatus which is capable of beingcontrolled in its indicating operations by devices, in this case timemarks on a card, which marks represent the data of the operation ofanother machine which has recorded in linear measurements the time ofthe beginning of the job, the time of the first operation of the saidother machine, also the time of the completion of the job, the time ofthe second operation of the said other machine; and also the elapsedtime occurring between the two said operations. In the present case, thedevices might be other than identification marks on a card and anysuitable device could be used for setting such devices and suchidentification devices might represent other values than those of time.The particular machine shown in the drawings herein and moreparticularly described hereafter is intended, however, to cotiperatewith another machine devised by me forming the subject-matter of anotherapplication for patent executed and filed simultaneously herewith. Insuch other machine, time marks are made upon a card in the form of holespunched therein, one hole representing in its linear position on thecard the time of the first operation, of the said other machine and theother hole: representing in its linear position on the card the time ofthe second operation of the machine, and thelinear distance between thetwo punched holes representing in units of linear measurement theelapsed time between the two operations.

The particular apparatus shown herein is, in its -1ndicatin -o erations,controlled by such a card an indicates the values rep're sented by suchholes by printin upon the card the time of the first or .in operation,the time of the secondor out operation and the time in hours and minutesof the elapsed time between the two. My invention has further forits'object to provide'new, improved and simplified means for operat ingdevices for indicating the difference between two operations of amachine as, for example, a machine for indicatin elapsed time; also theuse of a difi'erentia in such connection; also new and improved meansfor indicating the time of the in and out operation ofzsuch a machine;also generally to improve and simplifyTand make more'durable and certainin operation the various parts-of such a machine.

My invention consists in the novel devices and combinations herein setforth.

I will now proceed to describe the pre-' ferred form of my inventionwhich is embodied in the drawings accompanyin this specification andforming part hereo In the form here shown my improved apparatus isintended to translate into printed characters the time of the in and outoperations and theelapsed time occurring between the two said operationsof a machine, such as is shown in my said accompanying application ofeven date herewith, from the data representing such times as indicatedin time marks, as shown by holes punched in a card, representing inunits of linear measurements such times. Such a card with its time markson it is shown inFig. 14. As there shown, the card is provided with fourholes, holes 202 and 203 representing in linear measurements the time ofthe i in and out operations of the machine referred to in hours, andholes 204 and 205 representing similarly the minutes of the in and outoperations of said machine respectively. The card shown in Fig. 14 thusprovided with the punched holes is inserted in my improved machine ofthe-present applicatiomand by the operation of that machine the timedata represented by the said four holes in their *R'rtrfiii we theparticiilar embodiment shown in the drawings, Figure 1 isa frontview ofa preferred form of my improved device showing. the operatinghandle.;1,the slot 3. into which thecard i's insertedand the twosmallcranks 4 and 5 by which the ink ribbon'i's movedor fed. i

Fig. 14 shows a card after it has been treated by the machine describedin my accompan'ying application and before it is insorted in theinachineof the present application.

Fig. 15 is a view of the same card after it has been subjectedto'treatment in the machine of the present application:

1 is the operating handle, 2 the casing and 3 the slot into which thecard to be operated upon is inserted by the operator. 4 and 5- arehandles for moving. the inkribbon 56 irr' 'eitlier"direction as desired.Of course any suitable mechanism for feeding the ink ribbon could beemployed, and for reversing its feed, either automatic or manual. I havein the present case simply shown a manual device for feeding the inkribbon in either direction at will. It will be understood that theshafts of each of the hand'lesr and- 5 carry the respective rollers uponwhich the ink ribbon is mounted at either end. I

v 1 is secured directly upon the main driving shaft 6. of the machine,upon which shajft are mounted the various cams for operating thedifferent parts of the machine and which cams are all reciprocatcd asthe shaft reciprocates under the operation of the handle. .In practice,the operator seiaes the handle 1 and pushes it backward to the limit ofits movement, and then moves it forward again, or in case he fails to dothis, wholly or in part, it is brought back with all of its connectingparts to its original position by means of a spring 40, shown in Fig. 2secured at one end to a standard forming part of the frame-work, and atthe other .end secured to an arm fast on shaft 6.

Before proceeding to describe further in detail the mechanism shown, andin order to make the explanation clearer, I will briefly describe thegeneral operation of the machine.

After the operator has fully inserted the card in slot 3; he gives thehandle 1 the reciprocating movement above described. Through variouscams and connecting parts, this causes the'entire operation of themachine. Among other things, it brings down upon the card the four setsof pins 106 and 169 of the two pin boxes 109 and 170. 109 is thehou-r'pin box and is provided with two parallel rows each of twenty-fourpins 106, one set in alinement with each of the two lines 212 shown onthe card, Fig. 14, and pin box 170 is similarly provided with twoparallel rows, each consisting of sixty pins, 169 in alinement with thetwo parallel lines 213 of the card when the latter is inserted in theslot. These pin boxes have an up and down reciprocating movement.Shortly after the main shaft starts in its initial-movement, these pinboxes are moved downward through a cam mechanism, so that the pins arebrought down upon the card. Each pin is arrested in this position bythe'cardunless it happens to be in alinement with a punched hole202,203, 20 2 and 205. If in 'alinelnent with one of those holes, thepin projects through the card and through a hole in carthplate 22.

There will, therefore, at this juncture be four pins projecting throughthe four openings in the card and the corresponding holes in plate 22and projecting slightly beneath the latter as shown in Fig. 13. Thesepins serve to stop devices, which in the present case are shown asselector blocks 121, 122, 123 and 124 and the location of such devicesin their stopped positions controls the characters appearing on theprinting type wheels which print the time shown on the card in Fig. 15.

Shortly after the beginning of the rotation of the main shaft, animpulse movement causes a carriage 63 to move backward along a guide rod26. This carriage is detachably connected with each of the four selectorblocks so that the carriage moves each selector block along until aprojection, 72, from the selector block strikes one of the projectingpins. This causes the selector block to be detached from the carriageand to be locked in its set position. Each selector block is connectedto one side of a diffcrential gearing, the two hour selector blocks 121and 122 being connected respectively by levers 129 and 78 and links 125and 77 and their connecting parts to an hour differential shown in Figs.6-10 upon opposite sides and so as to move their connecting parts of thedifferential in opposite directions in the usual way. Similarly theminute selector blocks 123 and 124 are connected by, levers 127 and 131.respectively and their connecting parts to opposite sides of a minutedifferential constructed in all respects like the hour differential andshown at the right in Fig. 4. In the case of each differential, theresultant movement either one way or the other of the differentialthrough suitable gearing moves the corresponding elapsed-time type wheeland through suitable gearing connected with the gears on the oppositesides of the differential the wheels for printing the hour and minute inand out time are operated in accordance with the extent of movement ofthe respective selector blocks.

These operations cause to be printed upon the card when the printingpressure devices are subsequently operated, the times for the in and outoperation of the machine which produced the time marks on the card shownin Fig. 14, and also the elapsed time between the two operations of saidmachine.

As the main shaft rotates still further in its operation. by suitablecam mechanism, the printing pressure pads 23 (Figs. 2, 4 and 5) arebrought into operative position to effect the printing.

All of the parts are then returned to their normal position by thebackward movement of the main shaft 6 and operating handle 1. as alreadydescribed. 1

I will now proceed to describe more in detail the different parts of themechanism.

I will first describe the carriage and its impulse mechanism. It isspecially illustrated in Figs. 3, 4, 5.

Oarm'age and connections.

142 is an arm fast on shaft 6 and having a curved projection 215. Arm142, of course, turns with shaft 6. 141 is a rocking piece loose onshaft 6. It carries on its two arms and looselv pivoted to it two pawls143 and 144, the first pivoted to-it at 150 and the second pivoted to itat 151, each pawl is provided with a tail or end piece at'each end, thepawl 143 having the two tail-pieces 149 and 146 and pawl 144 having thetwo tail-pieces 147 and 148. In the position of the parts shown in Fig.3, the pawl 143 has been rocked on its pivot 150 slightly to the rightso that tail 146 is projected inward and lies against the inner surfaceof extension 215 while the other end or tail 149 is thrown into thenotch 44 in sector 145 secured to brackets 43 and 40 forming part of theframe-work of the machine. As arm 142 begins to rotate as soon asextension 215 passes the end of tail 146, it strikes tail 147 of pawl144 and starts rocking piece 141 forward. This moves the end of pawl 143from engagement with stud 42 on bracket 43 and thereupon spring 142which is secured to the tail 149 of pawl 143 and tail 148 of pawl 144causes pawl 143 to rotate to the left. bringing tail 146 immediatelvbehind extension 215 of piece 142. The parts are thus locked firmlytogether. The movement of piece 141 is communicated to carriage 63 bymeans of link 61 secured to sleeve 140 to which rocking piece 141 isfastened and also through link 62 pivoted at the other end to link 61and to carriage 63. The initial movement of rocking piece 141 thuscauses carriage 63 to move toward the rear of the machine along guiderod 26. In order to insure the carriage remaining in an uprightposition, there is fastened to it an upright arm 64 which straddles atits lower end the guide rod 28.

Motion is transmitted from the carriage to each one of the selectorblocks. in the following manner The selector blocks and theirconnections.

ing on rods 159 and 160. block 122 sliding on rods 79 and 80, block 123sliding on rods 161 and 162. and block 124 sliding on rods 163 and 164.

For each selector block the carriage has a draw-bar 65, see Fig. 13.Connections are provided between each selector block and itscorresponding draw-bar for connecting the selector block and thedraw-bar at times, and for disconnecting them. As shown, thesedetachable connections are as follows". In Fig. 13 are shown the hourselector block for the out operation and its corresponding draw-bar 65.As all of the selector blocks are connected with their draw-bars in thesame Way, I will describe only the connections for the hour out selectorblock. 74 is a locking pawl for locking the selector block to thedraw-bar. It is fulcrnmed in the selector block at 216 and has a tail 76which in the position of the parts shown in Fig. 13, takes into acorresponding notch out toward the rear end of draw-bar 65. In thisposition of the parts. motion is communicated to the selector block fromthe draw-bar by the rear wall of the notch pressing against tail 76 andforcing the selector block forward. The selector block is released bymeans of a trip-lever 72 fnlcrnmed at 216 in the selector block. Itsupper part forms the trip finger adapted to engage with any pin of thecorresponding set that happens to project downward through a hole in thecard 108 and the corresponding hole in card-plate 22. Trip finger 72 isshown in Fig. 13 as about to engage such a depressed pin. When finger7E2 strikes a pin the lever is rocked on its fulcrum and a pin 73 whichprojects sidewise from lever 72 and which lies normally opposite aprojection 69 forming part of locking lever 74 rocks projection 69 andwith it lever 74 to the left and withdraws tail 76 from the notch ofdraw-bar 65. The selector block immediately stops. It and its connectingparts are immediately locked in such position by the upper righthand endof lever 74 entering into and engaging with a notch in a locking bar 166(not shown in Fig. 18 but shown in crosssection in Fig. 5). There arefour of these locking bars, one for each selector block, 165 for the inhour selector block, 166 for the out hour selector block, 167 for the inminute selector block and 168 for the out minute selector block. One ofthe these selector blocks, 122. is shown in side view in the sectionshown in Fig. 3. Each of the selector blocks is supported in the frontand back frames 30 and 29 of the machine. The two hour locking bars areprovided with twenty-four notches each, and each of the minute lockingbars with sixty notches.

As the projection of lever 74 would only remain in engagement with thenotch as long as tail 76 was pressed downward by the under surface ofdraw-bar 65 back of the notch, I preferably provide a secondary lockingdevice for holding lever 74 in engagement with the notch. This isaccomplished by a secondary lock 66 pivoted at 68 in the selector blockand provided with an downwardly projecting notch into which projects apin 75 projecting sidewise from draw-bar 65. Spring 67 connects thelever 74 with the secondary locking lever 66 and tends to pull the twotoward each other. As draw-bar 65 separates from its selector block, pin75 rocks secondary rocking lever 66 to the left and throws a V-shapednotch at the upper end of lever 66 into engagement with a V-shapeddownward projection from lever 74. This looks lever 74 in the notch.

On the return of the draw-bar on the return movement of the carriage,pin 75 enters the slot or notch in looking lever 66, tilts that leverforcibly to the right, disengaging the V-shaped projection of 74 fromthe notch in lever 66, whereupon spring 67 immediately pulls lockinglever 74 out of the notch. In the further return movement of thedraw-bar 65, a downward projection from it, 217, strikes a knobprojecting from the side of the selector block and forces the selectorblock back to its original position.

The pin boxes and conncctioiw.

Two pin boxes are provided, the hour pin box 109 and the minute pin box170. Each of these boxes is provided with two parallel rows of pins, thehour box with two rows of pins 106, each row composed of 24 pins, theminute pin box 170 with two rows of pins 169, each row consisting ofsixty pins. Each pin box is, as shown, made up of a light metalframe-work having an upper and lower projecting portions provided withholes in which are seated the pins and a vertical wall carrying theupper and lower portions and fitted so as to slide vertically on acasting 155. Vertical movement is imparted to each pin box up and downthis casting and up and down an extension of the same, shown in Fig. 4,the extension on the hour side being numbered 183 and on the minute side184. An upward lug 20 from each pin box also aids in guiding the pin boxin its vertical movement along casting 155 and its extensions. Theadjoining walls of the casting and its extension and the pin box and itslug are made smooth so as to move over each other readily. The means forgiving the vertical movement to the pin boxes will be presentlydescribed. The castings 155 connect the two supporting members 29, 30 atthe rear and front of the machine (Fig. 2) which supporting membersconnect and are supported by the two side frames, 119 and 120, of themachine (Fig. 4:).

Fastened in each casting 155 is a rivet, 172 on the hour side and 171 onthe minute, which rivets work in suitable vertical slots in thes'pinboxes 109 and 170 respectively and guide their vertical movement.

Fastened to the side of each pin box are two sets of springs which, asshown in Fig. 5, rest upon the tops of the pins and tend to depressthem. On the hour side these sets of springs are numbered 156 and 107and on the minute side are numbered 158 and 157. A punched-up lug on thelower part of each pin acts as a stop to prevent the pin from beingdepressed too far. The springs permit the'pins to yield upward when theystrike a card.

It will beseen that as the in boxes descend those pins that are inahnementwith a hole in the card will pass through and through acorresponding hole in-the card plate 22 and will project beneath thelatter. All the othenpins will be .st0pped by the card. The cardisaccurately guided to its position in the slot by the side Walls of thecard-plate 22 clearly shown in Fig. 5. The card is kept from rubbing aainst ink ribbon 56 by means of the sh eld-plate 118, which latter platealsoprevents the card sticking to the pins in case the latter shouldhappen to rub against the edges of any of the holes in the card. I

The mechanism for forcing the pin boxes downward and upward areasfollows: A cam 7 (Fig. 2) on main shaft 6 is provided with a cam-way inwhich runs a roller on the end of lever 8,, the latter fulcrumed at 9and having pivoted to its other end a link 10. Link 10 has pivoted toits upper enda crank-arm 11 fast to shaft 12 journaled in the sideframes of the machine. Also fast to shaft 12 -is a lever 13 connected bylink 14- with a crank-arm 16 fast to shaft 17 which is a shaft exactlylike shaft 12. Both shaft 12 and 17 have a pair of crank-arms 18. Thoseon shaft 12 are connected directly to the upward extensions on pin boxesat their inner ends. The two crank-arms 18 on shaft 17 are connected bymeans of the short connecting shaft 19 to the upwardly extendingprojections 20 of the pin boxes. Upon reference to Fig. 2 it will beseen that at the instant the machine starts into motion, the pin boxeswill be forced downward and the pins be brought down upon the card inthe manner alrea y described.

From the above it will be seen that the extent of movenfent of eachselector block will depend upon the location of the punched hole on theline on the card along which the selector block moves. This movement ineach case will represent the extentof time of the correspondingoperation of the machine which has punched the holes in the card, as forexample those shown on Fig. 14.

This distance is measured fromthe zero of time and on the card thiswouldbe represented by the beginning of the parallel lines 212 and 213shown at the bottom of the card in Fig. 14. On this card. this time isrepre sented inlinear measurements. This ls tran lated by the machineof-the present application into a movement of gear wheels and typewheels to represent the time, or indicate the time, of the in and outoperation in printed characters upon the card as shown at the top andbottom of the card of Fig. 1.3, and the difference in extent of movementbetween the hour in selector block and the hour outlselector block andthe difference between the movement of the in minute selector block andthe out" minute selector block, is in each case translated into acorresponding movement of a, differential and through it to thecorrespondin movement of an elapsed-time type whee This difference inlinear measurement between the two hour punchedholes, 202, 203, measuredalong one of the parallel lines 212,is thus translated into the numberof hours with which it corresponds and the said number is printed on thecard as shown in Fig. 15 where it is represented by the number 2.Similarly the linear distance or measurement between hole 204 and 205 onthe minute side is translated and printed as 28 min. It will, of course,be understood that, where an out hole in the card is nearer the zeroline than the corresponding in hole, the linear distance between the twoholes, representing the elapsed time between the two operations theyrepresent, is that measured from the in hole to the end of the parallellines at the top of the card plus the distance from the beginning orzero point of those lines near the bottom of the card to the out hole.The direct distance between the two holes is, of course, in such a casethe comple ment of the said linear distance which represent the trueelapsed time. In such a case the corresponding differential will, ofcourse, rotate in the opposite direction to thatit would rotate were thein hole nearer the zero point on the card than the out hole. And it willrotate an amount represented by said linear complement. This, in effect,subtracts the time value represented by said complement from the zero onthe corresponding elapsed time type-wheel and this is, of course, theequivalent of rotating said typewheel in the other direction on amountrepresenting the true elapsed time between the two operationsrepresented by said two holes.

I will now proceed to describe the means by which these times in linearmeasurement are, through the operation of the selector blocks,translated into the appropriate fig; ures through the movement of typewhee and a differential.

The difl'ere'ntz'al gear and connections.

The differential gear referred to is shown in Figs. 6, 7, S, 9 and 10 inparticular and in general also in Fig. 4.. Motion is communicated toeach differential preferably in a reverse direction by its correspondingselector blocks. For example, the differential gearing shown at the-leftin Fig. 4 which is the hour differential is connected on one sidethrough sector 130, sleeve 135 loose on shaft 15, and lever 129 and link125 with the hour in selector block 121. The same differential isconnected on its other side by sector 126, sleeve 137 on shaft 4'6 andlever 78 and link 77 with the hour out selector block 122. The minutedifferential. shown on the right-hand side of Fig. 4 isthussim-ilarlyconnected on one side with minute in selector block 123and on the other side with minute out selector block 124. In each caseone selector block moves one side of the differential in one directionand the 'other selector block moves the other side of the differentialin the reverse direction. The resultant movement of the difi'erentialone my or another represents the elapsed time between the "two pundhedholes in the card. and this movement is imparted through suitablegearing to the corresponding elapsed-time type wheel. For example, theresultant movement of the hour diiferential 'is communicate through gear178 to the hour elapsed-'time type wheel 112 and the resultant movementof the minute differcritial is communicated through gear 179 to theminute elapsed-time type wheel 113.

The movement of the hour in selector hlock .121, which represents thestarting yrs time hours is at the sameftime, through gear 193, connectedwith the differential 'to the in hour type wheel 114, and the .extentofmovement of the selector block 122, which represents the time of thesecond or out operation represented by punched hole 203 on Fig. 14, iscommunicated to the out hour time type Wheel 110 through gear 187 on theopposite side of the hour differential. In a similar manner theappropriate movement is communicated to the minute type wheelrepresenting the time of'ithe in operation of the machine, 115. and tothe out minute time type wheel f'r'om appropriate gears on oppositesides of the minute differential.

I will now proceed to describe this mechanism in greater detail. Figs.6, 7, 8, 9 and 10 are views of the hour difierential. It will beunderstood, of course, that the minute differential is con- ..structedexactly the same only with the parts facing the other way. 176 is thecentral stud of the hour differential which is secured to the side frame119. Upon this stud are mounted the gears composing the differential orconnected with it. Meshing with a gear 192 is a sector 130 secured to asleeve 135 loose on shaft 15. -An arm 129 fast on the sleeve isconnected by link 125 to the selector block 121. Fast with gear 192 is alarge gear 193 and a smaller gear 194. Gear 193 transmits movement tothe in hour type wheel 114 through gear 180 and shaft 117 upon which isfast the in hour ty'pe wheel 114.

The smal l gear 194 is a part of the differential ear proper. Alsoloosely mounted on stud 176 is the supporting member 190. It -isprovided with three arms radiating trom the-central hub. each armdrilled near its outer end for the reception of the pin 19-1. The tihreepins 191 are riveted into the ring 189 on one side and into thering-gear 188011 the other, so that all three form part of one structureand rotate together on the =eommonstud 176. Also riveted into the ri'ngs188 and '189 are the centers or'studsfor the two floating gears of thedifferential, 197 and 199. 0m these studs are mounted *loosely -pinions1'96-"an'd' 198 which are in mesh with each other. The pinion 196 isalso in mesh with the gear 194, WhiLl-ethe pinion 198 is in mesh withgear 195. Gears 195, 185 and large gear 187 are securedtogether and aremounted loosely onstud 176. Gear 185 meshes withfsector 126 fast onsleeve 137 loose on sh-a-ft 46, which sleeve also carries arm 78 andthis through l-ink 77 is connected with the hour out selectorblock 122.

Gear-187 turns the hour out type wheel 1'10 through gear 200 fast. onthe slurft 116 of the hour out type wheel. The extent of movement fofthe hour out type wheel is thus "dependent upon the extent of movementof the hour out selector block 122. It will. of course. be understoodthat the ,gears 194 and 195 on the opposite sides of the differential,beingmoved in reverse direction according to the respective extents ofmovement of the hour selector blocks 121 and 122, Wlll cause the rings189 and 188 and the supporting member 190to move a distance equal to thedifference between the respective movements of the two selector blocks,a distance, of course, representing the elapsed time between the twooperations which the movements of the selector blocks represent. Thismovement is transmitted to the hourelapsed-time type whcel 112 from[gear 188 tl1'rough a gear 178 fast on sleeve 186 to which the said typewheel is also secured. the resultant movement of the diflerentialis. ofcourse, only one-half that of the actual difference between the twomovements of the selector blocks, it is necessary to compensate for thisby making the gear 178 one-half the size of the gear 188 in the usualWay.

The result of the above operations is to bring upon the printing linethe hour in type wheel and the hour out type Wheel in such a manner asto bring the hour of the in or first operation of the machine and thehour of the out or second opera tion of the machine upon the printingline forthe in and out operations respectively as illustrated in Fig.15, and also to move the hour elapsed-time type wheel to bring theproper elapsed hour upon the printing line of the elapsed time as shownin Fig. 15.

As shown in Fig. 15, the in time printed at the top of the card is 9 08,which represents the time measured in units of linear measure,represented by the in hour and minute holes 202 and 204 on Fig. 14.Similarly, the out time printed at the bottom of the card in Fig. 15 is11 36, which is the time represented by the out hour and minute holes203 and 205 of the card shown in Fig. 14.

Similarly, the elapsed time printed on the card at Fig. 15 near themiddle of the card is 2 hours and 28 minutes, which represents theelapsed time represented by the linear distance between the hour andminute in and out holes of the card at Fig. 14, measured along one ofthe parallel lines of that card.

The construction and operation of the minute differential and itsconnections with the minute selector blocks and with the minute typewheels are identical with those of the hour differential and itsconnections, and therefore need not be further explained except to saythat in minute selector block 123 is connected with one side of thedifferential through a link, not shown but just like link, 77, on thehour side; also by arm 127, sleeve 138, loose on shaft 46 and sector128, and minute out selector block 124 is connected with the other sideof the minute differential by means of a link, not shown but just likelink, 125, on the hour side, arm 131, fast on sleeve 136, loose on shaft15, and sector 132, meshing with the other side of the minutedifferential; and the minute elapsed type wheel is driven from the gear188 of the minute differential through gear 179 on the sleeve 218 of theminute elapsed type wheel 118; also that the minute in type wheel isdriven from gear 193 connected with the minute diifercntial through gear181, which is fast on the sleeve carrying the minute in type wheel 11:and the minute out type wheel 111 is driven from gear 187 of the minutedifferential through a gear, not shown, fast on the sleeve.- of the saidminute out type wheel.

It is also obvious that instead of causing the movements of eachdifferential to be in opposite directions in accordance with the valuesrepresented by its time devices respeetively, the two movements of thedifferential might be in the same direction provided that in such caseone of said move ments was the complement in extent of the true valuerepresented by one of the time devices.

In case the out selector minute block is stopped by a pin before the inminute selector block is stopped, it will be seen that the resultantmovement of the differential and therefore of the minute elapsed-timetype wheel will be backward and not forward, and it will be understood,of course, that in such a case it will be necessary to subtract one unitfrom the-extent of movement of the elapsed-time type wheel on the hourside. Any suitable mechanism for subtracting one from such movement ofthe said wheel can be employed. I will now proceed to describe mypreferred mechanism, which is that shown in the drawings.

In the particular machine shown in the drawings each diiferential isoperated by its selector blocks which are controlled by the timedevices. ll'ly invention, however, is, of course, not limited to such aconstruction or connection. The differential may be operated by anysuitable means, and either automatically or manually. as long as suchoperation is controlled or limited by the time devices.

Subtractor mechanism.

This mechanism is particularly shown in detail in Figs. 2, 4, 11 and 12.Fast on shaft 6 is a cam 81, having a cam path in which travels a roller82 on the end of arm 48, fast on a stud shaft 219. Also fast on thisshaft is another arm 47, carrying at its end and pivoted to it a link25, which at its other end is pivoted to an arm 83, fast on a stud shaft8.4. Also fastened on this same shaft is an arm 85, carrying at its enda springheld pawl 90, pivoted at 87 and provided with a spring and astop arm 89 and a stop 88. At every operation of the machine the pawl 90is raised and lowered. is a ratchet wheel connected with the hourelapsed-time type wheel, as will be presently described, and adapted toturn that wheel backward one point or unit whenever the pawl 90 engageswith it. Normally pawl 90 is prevented from engaging with it by means ofthe shield 97, fast on shaft 94; but whenever it becomes necessary to'subtract one from the hour elapsed-time type wheel, as in the case setforth above, shield 97 is withdrawn from its shielding or protectingposition, by means presently to be described, and in that case pawl 90as it rises turns ratchet wheel 95 backward one point or unit, thussubtracting one from the hour elapsed-time type wheel.

The detailed mechanism by which this is accomplished will now bedescribed. 100 is a shaft mounted in the side frames of the machine,carrying a lever arm 103, the end of which is mounted directly in thepath of a pin 104 secured to the side of the minute elapsed-time typewheel 113. In the normal position of the parts pin 10:1 rests againstthe end of lever arm 103. If the minute elapsed-time type wheel turnsforward, as it does in the illustration given in Figs. M

and 15, pin 104-. will move away from lever 103 without affecting thatlever in any way, and on its return will simply be brought back incontact with it and without disturbing it. If, however, the minuteelapsedtime type wheel is moved by the differential backward instead offorward in which case, as already described, it will be necessary tosubtract one from the elapsed time in hours, pin 104 will rock lever 103slightly toward the right, as viewedin Fig. 12, and will rock in thesame direction lever arm 99, which is also fast on shaft 100. 105 is aprojecting arm with a notch in its end, in'whi'ch notch the end of leverarm 99 normally rests. Arm 105 is fast to shaft 94. Levers 'l03 and 99are held in their normal positions against pin 104 and hook 105respectively by means of a spring 101, fast to arm 102, secured to shaft100. Shield 97 is also fast on shaft 94. A spring 91, fastened to theframework and to shield 97 tends to pull theshield out of its rotectingposition. This'tendency is norma ly counteracted by arm 99 locking shaft94 from rotation by means of the hook 105. 'Whenever, however, P111104rocks the levers 103 and 99, as described, shaft 94 is unlockedandshield'97 moved by spring 91 from its protecting position. This isaccomplished, of course,- immediately after the elapsed-time type wheelshave been moved totheir said position. Immediately after this, cam 81causes pawl'90 to operate, and in the position of the parts justdescribed this pawl will move ratchet 95 one point backward.

This motion is communicated to the elapsed-time typewheel as'follows.Ratchet wheel 95 is loosely mounted on the shaft 98 of the elapsed-timetype wheel 112, and is connected by means of sleeve '53 with the wheel112 (see Fig. 5). 187 is a disk mounted on shaft'98 (see Fig. 4) closeto the ratchet wheel 95. It is connected to pinion 178 which is in gearwith the differential as described above. A spiral torsion spring 134 isconnected at one end with gear 178 and at the other end with ratchetwheel 95. Two rivets 96 are provided, projecting from ratchet 95 andprojecting into slots in the disk 187. These slots are just long enoughto allow the ratchet wheel to turn onetwenty-fourth of a revolution.Relative to the gear 187, from the description which I have given aboveit will be seen that when the minute elapsed-time type wheel turnsbackward, one will be subtracted from the hour elapsedtime type wheel.This operation takes place immediately after the type wheels have beenmoved to their respective set positions by means of the selector blocksand differential. Theprinting immediately follows this operation,whereupon all the arts are returned to their normal positions y means ofthe various cams on the cam shaft and their connecting parts. The shield97 is returned to its normal position by means of a cam 92 mounted onlink 14, striking a cam-shaped projection 93 from shaft 9 1. It will 'beremembered that link 14 was described in connection with the devices forforcing the pins down upon the card. In the return movement of link 11the cam 92 restores shield '97 toits original position, asjust-described.

V "Any suitable mebhanismmay be employed for effecting the printing bythe various type wheels. As shown, I accomplish this by means of a rod27 (see Figs. 2 and 4) on whichare mounted three pressure cams 23.Resting upon'th'ese cams are the pressure printing pads which are shownas mounted on the end offlat springs 24, secured to the under side ofthe card frame The rod 27 is journaled in the two end frames 29 and 30.A lever arm 34 is secured to the end of the rod 27 (see also Fig. and isconnected with the bell crank 32 by means of the link 33. 'On the opaosite end of the'bell crank is the link 31. he lower end of this linkis slit at 173 to straddle the lever arm 35. The latter lever is pivotedonthe casting'LOatBG and this lever at the end of its other arm 37carries a roller38, traveling in a cam groove inthe cam 39. As shown inFig. 2, the printing occurs the last thing in the cycle of operations onthe forward stroke or operation of the machine. After this occurs cams23 will be'rocked to the right, as shown in Fig. 5, and will press theprinting pads against the card, ink ribbon, and type wheels, and take animpression ofthe type which stands opposite them on the printing line.

In case the operator does not return handie 1 to its original forwardposition, I pro vide a strong spring 49 secured to anarm 50 fast onshaft 6 to effect this end. I also preferably provide spring 139 ('Fig.3) secured tothe'lower end of lever 61to aid in the return of thecarriage to its original position.

Any suitable device may be used for operating and reversing the inkribbon. As this forms no part of my invention I have simply shown amanual feed operation, which is illustrated at Figs. 2 and 3. 51 and 52are the two rollers which carry the ink ribbon 56, which are mountedrespectively on shafts 53 and 54, upon the ends of which outside of thecasing are mounted handles 5 and 4. The ink ribbon runs from one rollerto the other around various guide rods 55, 57 58, 59, and 60, andbetween the various type wheels and the shield plate 118, which protectsthe card and the ink ribbon from each other. It will of course beunderstood jthat this shield at the proper printing points is providedwith openings to permit the pressure of the pads to force the card andink ribbon together against the type.

Many modifications or changes in, additions to or subtractions from, theparticular devices shown in the annexed drawings and described herein,other than those that have been already specifically referred to above,-

may, of course, be made withoutdeparting from my invention.
